我有一个来自WordPress的contact-template.php文件...

表单有4个必填字段...

现在，如果任何或所有必填字段为空，表单将不会提交，用户将在每个为空的文本输入字段下面得到“此字段是必填的”消息。-这完全是我想要的

我遇到的问题是，当填写所需的字段，并点击“提交”按钮时，会有10-15秒的停顿，然后显示“谢谢你，我们会尽快回复你”的消息。

由于这种暂停，用户会多次单击submit按钮，并且每次单击都会发送一封重复的电子邮件。

我尝试使用“onclick=”this.disabled=true；this.value='发送，请稍候...“，但这跳过了输入字段验证，不允许发送消息。

我希望此按钮禁用并显示“正在发送，请稍候...”文本，但它需要验证文本输入字段并最终提交/发送电子邮件消息

请救命！！！

这是密码...
